Two helical springs of the same material and of equal circular cross-section and length and the number of turns, but having radii 20 mm and 40 mm, kept concentrically (smaller radius spring within the larger radius spring), are compressed between two parallel planes with a load P. The inner spring will carry a load equal to:
1
\(\frac{{8P}}{9}\)
2
\(\frac{P}{3}\)
3
\(\frac{P}{2}\)
4
\(\frac{P}{9}\)
